GRAIN-GAR DOOR.

Specification of Letters Patent.

Application filed November 26, 1917. Serial No. 203,962.

To all whom it may concern: Be it known that I, WILLIAM HERBERT TOOMER,a citizen of the Dominion of Canada, residing at the village of Elgin,in the Province of Manitoba, in the Dominion of their destination hasbeen reached. Further objects of the invention are to provide doors ofself-sustaining structure suitable for use with cars of standardconstruction and without change of the said cars in any particular toadapt them to the doors.

Doors made in accordance with my invention may of course be used formany purposes other than that mentioned, but as their most outstandingutility-appears to be in connection with box or grain cars, thedescription to follow will be confined to that connection.

The invention in the main consists of two members, similar in allrespects, adapted when in position in the door opening of a grain car,to overlap on each other and on the posts at the sides of the dooropening, and having means whereby they are releasably united untildischarge of the contents of the car becomes desirable.

The means by which the said objects are attained will be foundhereinafter first fully described in the following specification andthen more particularly pointed out in the appended claims, referencealso being had to the drawings forming part hereof. in which similarcharacters of reference indicate similar parts throughout the variousviews, and

. in which- Fig. 1 but from the inside of the car.

Fig. 3 is a section taken on the line 3 in 1 and looking downward.

Fig. '4: is a view similar to that in Fig. 3, but the door being shownin the act of opening outwardly to discharge the contents of the car. 1

Fig. 5 is an edge view of one of the door members.

Fig. 6 is a view of the outer side of the same door member.

Fig. 7 is a view of the opposite or inner side of the said door member.

Fig. 8 is a sectional view through the center of one of the lockingmembers.

In the drawing 1 indicates the floor of the car having the door opening2 with the vertical posts 3 and 4t at each side thereof connectedat thetop by the cross beam 5.

The door 6, the subject matter of the present invention, consists of theouter and inner members 7 and 8 of similar construction and proportionsthroughout, the said proportions, in so far as shape and height areconcerned conforming to those of the con ventional grain car door, butthe length of the sections being somewhat less than the width of thedoor opening.

The member 7 is provided with a cross bar 9 positioned back from-the endof the member to leave a projecting end 10 of the 1 body. portion of themember, and a second cross bar 11 at the opposite extremity-of the saidmember, the latter being preferably secured in position by nails orother suitable simple means, and the former by the bolts 12. Similarly,the said member 8 has the cross bars 13 and 14: similarly positioned andsecured thereto, and leaving the projecting end 15 of the member. Thecross bars 9 and 13 are thick and those 11 and 14am so proportioned thatwhen their thicknessis added to that of the member to which they aresecured the combined thickness is equal to that of the members 9 and 13,so that when the'door members are overlapped as shown in the drawings,the outer face of the cross bar 11 on the door member 7 comes flush withthe face of the cross bar 13 on the member 8.

16 indicates a plurality of locking mem- .bers pivotally secured to theface of the cross bar 13 on the door member 8 in the present instance,preferably by means of the bolts 17, the locking members being thickenedat their lower ends to weight them,as is best shown in Fig. 8, and so toprevent unpremeditated rotation of the said members. The locking membersarealso formed. with a lateral projection 18 at the top, which may bestruck with ahammer or, other instru-.

' ment to rotate the saidmember.

19 indicates a plateof metal secured to the It should here be notedthat-the cross bar 9 on the door member 7 might be provided with-lookingmembers similar to those 16 on the member 8,in which case the said doormembers would be interchangeable as to their relative positions in thedoor and either jcould be usedzontheoutside. Asf it would have been amere duplication to have shown the locking members on the other doormember this has not been done. 7

faces of the projecting ends 10 and of the :door members preferablybymeans of the bolts 20, the plates being let into the said members tocome flush with their'faces as shown in the drawings, or secured to thesurfacesthere'of as'may-be deemed most desirable. T-he plates 19 areperforated as at 21 and the "perforations may continue fthrough thethickness of the door member 1 as is 'shown in Fig. 6, the saidperforations providing means whereby nails orspikes '22 "may be passedthrough and driven into the points, it will'be noted, being closely adjaposts 3-a'nd lat definite points; the said cent the extremities of thedoor members and *the' inner face of the post 3 and the cross I I 1 bar;9 abutting the side of the post facing the dooropening' 2. The member8-is next set-up overlapping the inner side of the -n ember-' 7 and withits projecting end '15 overlapped on the post 4' and its crossbar 13butted against the side face of the same. The length of the door memberis such that when in this pos'itio'n the extremity of the member 7having the cross strip 11 secured 'thereto,justjreachesthe cross bar 13on-the "member 8. The'flo'cking members 16 are {next rotatedcounter-clock-wise a quarter turnby hand, thus permitting the 'endof the1 member 7 to enter behind the bar 13 and the faces of the strip 11 andcross bar 13 to come "flush with each other, the locking members 16then, due to the manner in which they'are weighted, falling naturallyinto the position shown in full lines in the drawings, that is tosay,'across the dividing line between the strip lland the bar13 andsecurely connectingthefrespective door members 7 and 8 to ywhich thesaid strip and cross bar are secured.

With aweight of grain againstthe inner sides er themembers it is clearlyapparent thatthey would require 'no further support and that no movementof any kind. could take place to displace them. It is a fact however,that ,a certain proportion of shippers are not satisfied with a graincar door unless it is spiked to the car, the plates 19 withtheperforations 22 provide the means to gratify this wish andwithout dangerof either splitting the doors or damaging the car. 7 Y

At this point it should be noted, that as the outer door member is alever of the second class, fulcrumed on the door post 3 with the loadapplied closely 'thereto'through the cross strip 14c0n the member 8, thepower required from the locking members 16 to maintain the "door membersbonded against outv'aard pressure is very slight and no danger offailure at this point may be apprehended. During movement of the car orin loading it is also possible that the space "between the door membersmay become filled withgrain thus assisting thedoor members to functionas a unit v When it is desired to deliver the contents of the carzthe'locking members are rotated by striking their projecting portions18 with any instrument at hand, thus releasing the members-7 whichimmediately assume the 7 position sho'wnin -Fi'gac, the'door member Y'8, urged by the pressure following and the grain; pouring outthroughthe dooropening. 1 As the door' membersm'ove out the" vspikes 22are drawn bylever'age, as is shown in Fig. 4: and they-come away withthe door member and do not remain to prevent the placing of another doorwhen the necessity two of them will form a door suitablefor use with anycar having a door opening of standard width. Cars with door openings ofspecial width willre'quire doors of special dimension to match. i

j Having thus fullydescribedf said in- Ventiofn, what I claim isinterchangeable similar sections-overlapped oneachfother for a portionof the width of the door opening and upon the door-posts at the sides ofthesaid opening, a cross bar 1.
